Abstract
A 0.9-V input discontinuous-conduction-mode
(DCM) boost converter delivering 2.5-V and 100-mA output is
presented. A novel low-voltage pulse-width modulator is pro-
posed. The modulator can be directly powered from the 0.9-V
input instead of using the 2.5-V output as in general modulator
designs. Sophisticated low-voltage analog blocks, which normally
consume a large amount of power and chip area, are not required
in the modulator. The impact of output-voltage ripple and tran-
sient-induced outp
